FIG. 1 illustrates an example of method 100.

Method 100 is for three-dimension (3D) based shopping.

Method 100 may start by step 110 of receiving or generating a 3D representation of at least a part of a body of a certain customer. The at least part of the body may include the head, neck, torso, hand, palm, foot, leg, any upper part and/or middle part and/or lower part of the body.

Thus- step 110 may include receiving the 3D representation or generating the 3D representation.

The generating of the 3D representation may include receiving images of the at least part of the body. The images may be taken from different angles and the angular information (regarding the angles) may be explicitly or implicitly provided.

The 3D representation may include any type of information that may indicate of the 3D body part. It may include visual information and/or non-visual information. For example the 3D representation may include a set of coordinates that reflect the exterior shape of the at least one part of the body, or any other mathematical and/or visual model.

Step 110 may include creating the 3D representation by simple measurements according to the instruction. Most available, affordable and less precise.

Step 110 may include creating the 3D representation by different kind of scanners

Step 110 may include creating the 3D representation by by wearable “overall”, concluding special measurement sensors, located in the right places and allowed precise measurements. Wearable “overall” can be from for one time disposable until more prestige's models for personal using along the time. Sensors can be integrated inside the wearable “overall” for long time using and alternatively can be separated from the overall and “installed” at the right places only for the time and purposes of measurement [remains in possession of retailer]. All sensors will wirelessly transfer real data to the central computer and appropriated algorithms will translate these data into measurement units and 3D model. These measurements and 3D model can be used for purchase according to the present invention. Alternatively these measurements and 3D model can be used by specially designed for PC or/and smartphones applications for long time monitoring of body parameters and trends. Such use is especially attractive for those populations, who monitoring weight or/and other body parameters for the purposes of monitoring, control, feedback, research, etc. during various procedures, related to food consumption or/and physical training/activities

Step 110 may be followed by step 120 of receiving a query to find a first wearable item that fits the part of the body.

The query received in step 120 may be explicitly state that type of the first wearable item (for example—please find me a shirt) and/or may implicitly indicate the type of the first wearable item (for example—find may a wearable item that will fit a certain part of the body—or even find one or more wearable items that fit any part of the body that is included in the 3D representation).

The first wearable item may be selected from a footwear and a cloth.

The query may also list one or more properties of the first wearable item such as color, material, thickness, durability, softness, texture, a fit parameters (such as—tightly fit the part of the body, loosely fit the part of the body, and the like).

Step 120 may be followed by step 130 of searching for the first wearable item. The search is based, at least in part on the one or more properties listed in the query (if such one or more properties were indeed listed).

Step 130 may be followed by step 140 of displaying on a display that may be accessible to the certain customer a 3D model of the first wearable item when worn over the part of the body.

Step 140 may include using Virtual Reality [VR] in order to present customer various options based on it 3D model various parts-for-sale. VR is the computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors

Step 140 may include using Augmented Reality [AR] in order to present customer various options based on it 3D model various parts-for-sale. AR means a technology that superimposes a computer-generated image on a user's view of the real world, thus providing a composite view. Augmented reality is technology that combines virtual reality with the real world in the form of live video imagery that is digitally enhanced with computer-generated graphics. AR can be experienced through headsets that people wear and through displays on mobile devices

The difference between VR and AR: Augmented reality (AR) adds digital elements to a live view often by using the camera on a smartphone. Examples of augmented reality experiences include Snapchat lenses and the game Pokémon Go. Virtual reality (VR) implies a complete immersion experience that shuts out the physical world.

The Basics of How VR Works: The primary subject of virtual reality is simulating the vision. Every headset aims to perfect their approach to creating an immersive 3D environment. Each VR headset puts up a screen (or two—one for each eye) in front of eyes thus, eliminating any interaction with the real world

The goal of Augmented Reality is to create a system in which the user cannot tell the difference between the real world and the virtual augmentation of it. Today Augmented Reality is used in entertainment, military training, engineering design, robotics, manufacturing and other industries

AR makes the existing reality more meaningful because it allows to interact with it. Augmented reality has a great potential to be used in the classroom because it changes the way students interact with the realworld, enhances student engagement, and makes the learning of their subject content a fun.

Step 140 may be followed by step 150 of interacting with the certain customer till a completion of the 3D based shopping. Step 150 may include completing the 3D based shopping.

The interacting may include feedback regarding the first item—whether the first item is desired by the certain customer, whether the first wearable item should be adjusted, whether the first item is not desired and should be replaced by another wearable item, and yet may also include the provision of billing and/or ordering and/or packaging information.

The 3D representation may include a 3D representation of a part of the body that may fit the first wearable item but may also include a 3D representation of other parts of the body.

The interacting may include receiving feedback from the certain customer and updating a certain customer profile based on the feedback.

Method 100 may also include step 160 of searching, following a finding of the first wearable item, for at least one additional wearable item that may fit at least one other part of the body. Step 160 may be followed by step 150.

The at least one additional wearable item may be associated with the first wearable item. The association may indicate that these wearable items fit each other—based on various fashion rules and/or based on an identity of a vendor that supplies the wearable item, and/or based on a predefined association between the wearable items.

The searching of step 160 may be triggered by step 120 (even without an explicit request of the user to perform the search), may be triggered based on any feedback from the user, and may be based on an explicit request from the user.

Step 160 may be followed by step 170 of displaying on the display a 3D model of the at least one additional wearable item when worn over the at least one other part of the body. Step 160 may be followed by step 150.

Method 100 may also include step 180 of searching for non-worn items associated with the first wearable item and displaying information about the non-worn items to the user. Step 180 may be followed by step 150.

The searching of step 180 may be triggered by step 120 (even without an explicit request of the user to perform the search), may be triggered based on any feedback from the user, and may be based on an explicit request from the user.

Any one of steps 130, 160 and 180 may be based on a certain customer profile and/or may include utilizing machine learning processes. The outcome of step

Any one of steps 130 and 160 may include comparing dimensional information related to the first wearable item and to dimensional information related to the part of the body of the certain customer.

The first wearable item may be a configurable wearable item. Step 150 may be followed by step 192 of configuring, upon completion of the 3D based shopping, the first wearable item to fit the part of the body of the certain customer.

The first wearable item may be a 3D printer generated wearable item. Step 150 may be followed by step 194 of 3D printing, upon completion of the 3D based shopping, the first wearable item to fit the part of the body of the certain customer.

Method 100 may include creation, saving and sharing of various kind of 2D images from 3D model in various parts-for-sale.

Method 100 may include creation, saving an sharing “books” of customer in various parts-for sale

Method 100 may transforms a very boring [dull, tedious, tiresome] procedure of shopping into entertainment.

There wearable item may be a shoe that can be assembled from a kit of shoe parts that may be tailored to the foot of the user and may serve multiple functions. Multiple combinations of the shoe parts may provide shoes that differ from each other by functionality. The shoe parts may be fastened or connected together by fasteners or any other means.

The shoe parts may be selected in view of the shape and size of the foot of the person. The foot of the person may be scanned in order to determine the parts of the shoe. Additionally or alternatively, the parts of the shoe may be selected (with or without scanning the foot) based on parameters such age, weight, foot profile of the person and/or based on the function of the shoe (shock absorption requirements, purpose of the shoe—sport, social events . . . ).

Two or more parts of the shoe may be connected to each other to provide a shoe. The kit may include upper parts of the shoe, lower parts of the shoe and even intermediate parts of the shoe.

Wikipedia defines a shoe as including a sole, which is the bottom of a shoe, in contact with the ground. Soles can be simple—a single material in a single layer—or they can be complex, with multiple structures or layers and materials. When various layers are used, soles may consist of an insole (inner part of the sole—which sits directly under the foot, midsole (between the insole and the outsole), and an outsole (direct contact with the ground).

The insole may be attached to the lasting margin of the upper, which is wrapped around the last during the closing of the shoe during the lasting operation.

The shoe may include removable and replaceable footbeds. The heel is the bottom rear part of a shoe. Its function is to support the heel of the foot. The upper helps hold the shoe onto the foot. Most uppers have a mechanism, such as laces, straps with buckles, zippers, elastic, Velcro straps, buttons, or snaps, for tightening the upper on the foot. The vamp is the front part of the shoe, starting behind the toe, extending around the eyelets and tongue and towards back part of the shoe.

The medial is the part of the shoe closest to a person's center of symmetry, and the lateral is on the opposite side, away from their center of symmetry. This can be in reference to either the outsole or the vamp.

Most shoes have shoelaces on the upper, connecting the medial and lateral parts after one puts their shoes on and aiding in keeping their shoes on their feet.

The toe box is the part that covers and protects the toes.

According to an embodiment of the invention the kit may include parts that are selected out of a sole, an insole, a midsole an outsole, an upper, a heel, a medial, a vamp or a combination of said parts (for example a shoe part may include a heel and an upper).

A kit may include shoe parts that once assembled may provide a single shoe or may allow a user to provide multiple shoes (one at a time).

There kit may include shoe parts that differ from each other by type. Different types of a part may differ from each other by material, style, color, cost, structure, heating capability, durability, design, style, weather durability, and the like. For example the kit may include multiple types of soles-running soles, walking soles, elegant soles, and the like.

The kit may include a one or more interchangeable inserts that are may bridge a gap between the foot and other parts of the shoe.

According to various embodiment of the invention the kit may include:

-   -   a. Interchangeable bottom parts that may be designed based on         purpose (training—walking, running, trekking, etc.), and/or         based on health conditions (age, weight, foot profile, shock         absorption, etc.), and/or the presence of absence of an         interchangeable insert to be used.     -   b. Interchangeable inserts may be included in the kit and may be         adjusted for bottom part in use from one side and health         conditions from other side. Inserts are subject for timely         changing in accordance with timely/periodically 3D scan of         foots.

The kit may include interchangeable upper parts that are adjusted for various climate conditions, such as sun, rain, dust, sand, etc.

Parts A and C can be easily connected by quick click connectors or a type of connecting element.

FIG. 5 illustrates shoes 10, 11 and 12—shoes 10 and 12 have the same sole 21 but different upper parts 22 and 24 and shoes 10 and 11 have the same upper part but different soles—21 and 23.

In this way user can utilize endless combinations of parts A, B and C for more suitable solutions.

According to an embodiment of the invention there is provided a method that may include receiving information about a foot of a user. This may include 3D scanning and/or receiving less accurate information about the foot (such as size and/or general dimensions) and/or information about the user (age, weight) and/or the purpose of the shoe and manufacturing and/or retrieving shoe parts that will fit the user.

Today refunding of parts-for-sale, sent hack by customer to the seller is high. The major reasons of this is mismatch of purchased part or any other misfit to customer' expectation.

This is inherent phenomena of any internet [remote] retailing process, based on very limited presentation of parts-for-sale without any feedback, based on the real parameters of potential customer and it observation of how the part-for-sale will fit his expectations.

As the results of the proposed method, the quantity of returned parts-for-sale and related amount of refunding will be seriously reduced. This is one of the major positive economical outcomes of proposed method for any retailing business.

Current process of purchase of any part via internet is simple, boring and lucking of any interaction between internet retailing site and potential customer. Such method might be appropriate for selling books, movies and alike, but much less appropriate for purchasing of parts of wearing, accessory, shoe and alike.

Proposed method allow potential customer to create and most important—share between friends directly or by means of any available social network images of himself, wearing potential part, discuss it and get feedbacks.

Such possibility of purchasing method will increase drastically certainty of any purchase and reduce future requests for refund

It is also will increase traffic across social networks and involvement large population of potential customers in social networking.

FIG. 6 illustrates method 600 for creation of 3D Model of human body of potential customer.

Method 600 may start by step 610 of performing a measurement of various human body elements by any of measurement means.

For example:

-   -   a. Direct measurement each element of human body by scales,         available industrial stand alone and mobile measurement devices.     -   b. performing Image and border/boundaries recognition on/from an         image, acquired by any imaging means, including but not limited         Visible light, Infra-Red and/or Near InfraInfra-Red.     -   c. Wearing of specially manufactured overall part [seating very         tight on the potential customer body]. This overall part has         square or rectangular print. The measurement concludes: (a)         Imaging of the human/potential customer body with this overall         on it, (b) Recognizing borders of square or rectangular print,         and (c) measurement the X and Y size of each square or         rectangle.

Step 610 may include acquiring an image of potential customer face.

Step 610 may be followed by step 620 of saving the results of the measurement.

The results may be saved in various data structures, including but not limited to a data base that may include all measurement results.

An example of some entries of the database may include, for example:

Body Measurement Measurement Measurement Note # Element 1 2 N % 1 1 L1 C1 N1 I 2 2 L2 C2 N2 Ii 3 3 L3 C3 N3 Iii N N LN CN NN i−n

Any other representations may be made.

The measurements may be any one of size, radius, distance between different ends of an organ or a body part, and the like.

Step 620 may be followed by steps 628 and 632 that refer to obtaining an avatar based on some first potential customer parameters and then amending the avatar based on additional (second) potential customer parameters. It should be noted that the two steps may be merged to a single step of selecting the avatar based on all first and second parameters. The two phases allows to store a more limited number of avatars which may be modified but their storage may require less storage resources. Ant tradeoff between the number of avatars, the number of parameters used for retrieval of the avatar, a number of parameters used for adjusting the avatar can be provided. Any selection criteria for selecting an avatar and/or determining the manner that avatar should be amended and/or the evaluating of the success in evaluating the avatar may be provided.

Step 620 may be followed by step 628 of retrieving (for example from a library, stored in computer memory) a 3D model of human body (the model is referred to as an Avatar). The Avatar may be selected based on one or more criteria—for example a best matching Avatar that best suited to the potential customer type of body. The one or more criteria may include, for example gender, age, height and the like.

Step 628 may be followed by step 632 of altering (modifying) the retrieved Avatar to the results of real measurements of potential customer.

The method may proceed by step 636 of entering the DB representing results of real measurement of potential customer body into a Bernstein basis polynomials

Steps 632 and 636 may be followed by step 640 of calculating a new version of Avatar, altered by Bezier curve, based on the results of Bernstein basis polynomials calculation of step 636.

This final version of the Avatar provides far better representation [fine] of the potential customer body.

These steps (636, 640, and further illustrated steps 636 and 640) amount in entering multiple point [inputs] into the Bernstein polynomial (Maybe we should use this wording for both steps 636, 640, 770 and 780). This better adjusts the amended avatar to the customer body' 3D model.

Thus method 600 and 700 involve measurement, picking up the best suited avatar, altering the avatar by real measurement data and amending this already altered avatar by Bernstein polynomic and Bezier curves.

Step 640 may be followed by step 644 of storing the final version of the avatar.

The final version of the avatar may be presented to the potential customer and/or be manually or semi-automatically adjusted (step 648).

FIG. 7 illustrates method 700 for creation of 3D Model of potential Part for Sale (POS).

Method 700 may apply the same operations or different operation as applied by method 600.

Method 700 may start by step 710 of receiving customer request regarding: a single potential part for Sale or any combination of parts for Sale, or a specific Set of parts for sale.

Step 710 may be followed by step 720 of presenting the result of the request to customer after filtering according to the Customer preferences and selections.

Step 720 may be followed by step 730 of allowing the customer to select any part from presented set/part.

Upon approving, receiving (step 740) all specification data of selected part or parts.

Step 740 may be followed by step 750 of achieving from a library, stored in computer memory a 3D model of selected part for sale [Parts Avatar], best suited to the customer type of body according to the following parameters [but not limited] Gender, Age, Height, Weight.

Step 750 may be followed by step 760 of altering [modifying] a Part Avatar, representing best suited, but yet neutral Model of potential part[s] for sale body by part for sale specification data and adjusting this Part Avatar to the results of specific part for sale.

The method may proceed by step 770 of entering the specification data of selected part or parts into a Bernstein basis polynomials

Steps 760 and 770 may be followed by step 780 of calculating a new version of Avatar, altered by Bezier curve, based on the results of Bernstein basis polynomials calculation of step 770.

This final version of the Avatar provides far better representation [fine] of the selected parts of sale.

Step 780 may be followed by step 790 of storing the final version of the avatar.

Step 780 may also be followed by presenting on a computer display a new version of the modified Part Avatar, achieved as result of manipulations.

After the successful execution of methods 600 and 700 the following steps of presenting the 3D model of customer and potential part of sale may be executed:

-   -   a. Presenting on the computer display two 3D models separately         and it overlapping:         -   i. Of customer body, received as results of method 600.         -   ii. Of Potential part[s] for sale, received as results of             method 700.     -   b. Emphasizing of the differences between these two models by         any means including, but not limited to colors:         -   i. Red color where it's too tight         -   ii. Green color where it's too loose     -   c. Allowing customer to observe these two models, when a model         of a part for sale is actually wear on the customer body model         from any direction, angel, height or distance     -   d. Allow customer to select one or more [but not limited] of the         following options:         -   i. Accept         -   ii. Reject         -   iii. Next     -   e. Present combination of any parts for sale [already accepted]         -   i. Save for later decision         -   ii. Get 3^(rd) party Expert opinion         -   iii. Share across social and communication network         -   iv. Save and perform customer selection.     -   f. Communicate with shop/warehouse, where selected part[s] for         sale are located [stored]     -   g. Proceed to standard payment and shipment procedure     -   h. Allow customer to select another part for Sale and proceed         accordingly

Step 780 may be followed by step 790 of storing the final version of the avatar.

Step 780 may also be followed by presenting on a computer display a new version of the modified Part Avatar, achieved as result of manipulations.

Referring to the Bernstein polynomials—the Bernstein Polynomials are incredibly useful mathematical tools as they are simply defined, can be computed very quickly on computer systems, and can represent a variety of functions. They can also be integrated easily and pieced together to form spline curves that can approximate any function to any accuracy desired. Most students face polynomials for the first time at a very early stage of their studies and most likely recall them in the form:

P(t)=a ₀ +a ₁ t+ . . . +a _(n−1) t _(n−1) +a _(n) t ^(n)

This polynomial represents a polynomial as a linear combination of a_(n−i)t^(n−i) monomials. Notice that the set of functions {1, t, t², . . . , t^(h−1), t^(n)} forms a basis for this vector space—that is, any polynomial less than or equal to “n” can be uniquely described as a linear combination of these functions.

In order to discuss approximations to functions and curves later on in our notes, we first need to understand a specific commonly used basis for the space of polynomials, the Bernstein basis (named after Russian mathematician Sergei Bernstein), and discuss its many useful properties.

Bernstein basis polynomials A Bernstein basis polynomial of degree “n” is defined by

${{b_{i,n}(t)} = {\begin{pmatrix} n \\ i \end{pmatrix}{t^{i}\left( {1 - t} \right)}^{n - i}}},{i = 0},\ldots\;,n$

$\begin{pmatrix} n \\ i \end{pmatrix} = \frac{n!}{{i!}{\left( {n - i} \right)!}}$

Where (n/i) is the binomial coefficient,

Often, for mathematical convenience, we set

b _(i,n)(t)=0 if i<0 or i>n.

A linear combination Bernstein basis polynomials is called a Bernstein polynomial of degree n where “b” are the Bernstein coefficients

${B_{n}(t)} = {\sum\limits_{i = 0}^{n}\;{\beta_{i}{b_{i,n}(t)}}}$

After the successful execution of methods 600 and 700 the following steps of presenting the 3D model of customer and potential part of sale may be executed. FIG. 8 illustrates method 800. The method includes generating or receiving one or more models such as (a) a final 3D model of a customer body, and (b) a 3D model of the part of sale. This is followed by presenting the two models—separately or overlapping each other. This may be followed by emphasizing difference between the two 3D models. This may be followed by a decision—how to respond to the differences—which may be followed by saving the decision and/or any information regarding the 3D models, and or may be followed by processing with the purchase. These steps may be followed by repeating the process for the next part. FIGS. 9 and 10 illustrate various body parts and measurements.

The method may be executed by a computer readable medium that stores instructions that cause the computer to execute the method.

The method may be executed by a three dimensional printer, by a computer that sends printing instructions to a three dimensional printer, and the like.

Any reference to a system should be applied, mutatis mutandis to a method that is executed by a system and/or to a computer program product that stores instructions that once executed by the system will cause the system to execute the method. The computer program product is non-transitory and may be, for example, an integrated circuit, a magnetic memory, an optical memory, a disk, and the like.

Any reference to method should be applied, mutatis mutandis to a system that is configured to execute the method and/or to a computer program product that stores instructions that once executed by the system will cause the system to execute the method.

Any reference to a computer program product should be applied, mutatis mutandis to a method that is executed by a system and/or a system that is configured to execute the instructions stored in the computer program product.

The term “and/or” is additionally or alternatively.

In the foregoing specification, the invention has been described with reference to specific examples of embodiments of the invention. It will, however, be evident that various modifications and changes may be made therein without departing from the broader spirit and scope of the invention as set forth in the appended claims.

Moreover, the terms “front,” “back,” “top,” “bottom,” “over,” “under” and the like in the description and in the claims, if any, are used for descriptive purposes and not necessarily for describing permanent relative positions. It is understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in other orientations than those illustrated or otherwise described herein.

Any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality may be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality.

Furthermore, those skilled in the art will recognize that boundaries between the above described operations merely illustrative. The multiple operations may be combined into a single operation, a single operation may be distributed in additional operations and operations may be executed at least partially overlapping in time. Moreover, alternative embodiments may include multiple instances of a particular operation, and the order of operations may be altered in various other embodiments.

However, other modifications, variations and alternatives are also possible. The specifications and drawings are, accordingly, to be regarded in an illustrative rather than in a restrictive sense.

The phrase “may be X” indicates that condition X may be fulfilled. This phrase also suggests that condition X may not be fulfilled. For example—any reference to a system as including a certain component should also cover the scenario in which the system does not include the certain component.

The terms “including”, “comprising”, “having”, “consisting” and “consisting essentially of” are used in an interchangeable manner. For example—any method may include at least the steps included in the figures and/or in the specification, only the steps included in the figures and/or the specification. The same applies to the system and the mobile computer.

It will be appreciated that for simplicity and clarity of illustration, elements shown in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity. Further, where considered appropriate, reference numerals may be repeated among the figures to indicate corresponding or analogous elements.

Also for example, in one embodiment, the illustrated examples may be implemented as circuitry located on a single integrated circuit or within a same device. Alternatively, the examples may be implemented as any number of separate integrated circuits or separate devices interconnected with each other in a suitable manner.

Also for example, the examples, or portions thereof, may implemented as soft or code representations of physical circuitry or of logical representations convertible into physical circuitry, such as in a hardware description language of any appropriate type.

Also, the invention is not limited to physical devices or units implemented in non-programmable hardware but can also be applied in programmable devices or units able to perform the desired device functions by operating in accordance with suitable program code, such as mainframes, minicomputers, servers, workstations, personal computers, notepads, personal digital assistants, electronic games, automotive and other embedded systems, cell phones and various other wireless devices, commonly denoted in this application as ‘computer systems’.

However, other modifications, variations and alternatives are also possible. The specifications and drawings are, accordingly, to be regarded in an illustrative rather than in a restrictive sense.

In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word ‘comprising’ does not exclude the presence of other elements or steps then those listed in a claim. Furthermore, the terms “a” or “an,” as used herein, are defined as one as or more than one. Also, the use of introductory phrases such as “at least one ” and “one or more” in the claims should not be construed to imply that the introduction of another claim element by the indefinite articles “a ” or “an” limits any particular claim containing such introduced claim element to inventions containing only one such element, even when the same claim includes the introductory phrases “one or more ” or “at least one ” and indefinite articles such as “a” or “an.”

The same holds true for the use of definite articles. Unless stated otherwise, terms such as “first” and “second” are used to arbitrarily distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements the mere fact that certain measures are recited in mutually different claims does not indicate that a combination of these measures cannot be used to advantage.

While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
